The Aberdeen Proving Ground Military Reservation dominates the landscape of Harford County, showing a complex of military infrastructure along the Chesapeake Bay. Settlement patterns center on Perryman and Stepney, where the Pennsylvania and Baltimore and Ohio railroads intersect the coastal plain. Local heritage is visible in the placement of the Spesutie Church (Cem), Perryman School, and the inland Harford Furnace School. Along the shoreline, the map identifies small points and coves like Chilbury Point and Romney Creek, alongside the coastal settlement of Old Baltimore. The transition from agrarian life to military facility is evidenced by labeled sites such as Ford's Farm and Phillips Field situated near the proving grounds.
